Internet Service Provider

For a monthly fee, an Internet service provider allows you to send and receive information from your computer to their computer, which is connected to the Internet, using a modem.
A business that supplies Internet connectivity services to individuals, businesses, and other organizations. Some ISPs are large national or multinational corporations that offer access in many locations, while others are limited to a specific city or region.
